FIFA has said it is "very concerned" at the findings of an investigation into the treatment of migrant workers in Qatar, hosts of the 2022 World Cup.
The world governing body will contact World Cup organisers and discuss the findings next week after The Guardian produced a report and video alleging that Nepalese workers in Qatar "face exploitation and abuses that amount to modern-day slavery".
FIFA said in a statement: "FIFA is very concerned about the reports presented by the media regarding labour rights' abuses and the conditions for construction workers in projects at Lusail City, Qatar.
"FIFA will again get in contact with the Qatari authorities and the matter will also be discussed at the executive committee meeting."
The executive committee is due to decide on the principle of moving the 2022 World Cup in Qatar to the winter, at its meeting in Zurich next Thursday and Friday, and it will now discuss the issue of mistreatment of migrant workers at the same time.
The investigation caused consternation in Qatar and World Cup organisers said they were "appalled" at the findings.
The Qatar 2022 Supreme Committee said while construction directly related to the World Cup had yet to start, it was committed to providing proper treatment for workers.
In a statement, the Supreme Committee said: "Like everyone viewing the video and images, and reading the accompanying texts, we are appalled by the findings presented in The Guardian's report.
"There is no excuse for any worker in Qatar, or anywhere else, to be treated in this manner. The health, safety, well-being and dignity of every worker that contributes to staging the 2022 FIFA World Cup is of the utmost importance to our committee and we are committed to ensuring that the event serves as a catalyst toward creating sustainable improvements to the lives of all workers in Qatar."
The statement said that the Qatari government is conducting an investigation into the allegations.
It added: "We firmly believe that all workers engaged on our projects, and those of the other infrastructure developers in Qatar, have a right to be treated in a manner that ensures at all times their wellbeing, safety, security, and dignity.
"This is our top priority as we begin to deliver on the promises made in our bid to host the 2022 FIFA World Cup in Qatar."
